MSHA-Approved Type G-GC 2000V Cable - 3-Conductor w/Ground-Check, Flat CPE for Mining & Tunneling
Product Overview
The Type G-GC Power, Flat Parallel Portable Cable is a rugged, MSHA-listed trailing cable designed for AC-powered mining equipment requiring fail-safe ground monitoring. Featuring three EPR-insulated power conductors, a dedicated ground-check conductor, and an ultra-durable CPE jacket, this cable ensures reliable performance in extreme conditions. Rated for 2000V and 90°C operation, its flat parallel design resists crushing, oil, and abrasion, making it ideal for mining, tunneling, and heavy industrial applications.

Construction Details
-
Conductor:
-
Material: Tinned annealed copper for corrosion resistance and flexibility.
-
Stranding: Rope-lay stranding (ASTM B172) withstands repeated bending and vibration.
-
-
Insulation System:
-
Power Conductors: Ethylene Propylene Rubber (EPR) for high-temperature stability (90°C) and resistance to oils/chemicals.
-
Ground-Check Conductor: Yellow elastomer insulation ensures easy identification and compliance with ground monitoring requirements.
-
Grounding Conductor: Green elastomer insulation, shaped to prevent movement within the flat assembly.
-
-
Jacket:
-
CPE: Lead-cured, flame-retardant jacket offers superior cut, crush, and environmental resistance.
